Apply Canada visa from Paris ! Do i have to go back to India and do it ?

Hi, I am an Indian citizen with an Indian passport and currently on a 6 month, multiple entry, Shenzhen visa (Class C) to Belgium (Antwerp). My query is I want to travel to Canada (British Columbia – Vancouver) can I apply for a tourist Visa from the consulate in Paris or do I have to return to India and apply from there.

Please let me know, i tried contacting the consulate in paris, but i havent really got any concrete information. Thanks a ton.
